'coan snvnnme IMPLEMENT 7 Application filed April 7,

This invention relates to improvements in implements of the type usuallyreferred to as emasculatomes of the type shown and described in UnitedStates Letters Patent No. 1,7 54,241, granted April 15, 1930.

The object of this invention is to'produce an implement of the typementioned which shall be'so constructed that it will be very rigid andtherefore reliable in itsoperatio-n and which shall also be soconstructed that it can be readily disinfected and cleaned. I

The general object of inventions of the type to which this improvementrelates is to provide means for severing the spermatic cord of animalsand also for severing the umbilical cord at birth.

Instruments of the type referred to are so constructed that they willsever the spermatic cord without cutting the skin in which it isenclosed so that this operation'can be aerformed without cutting andsubsequently without loss of blood. V

In instruments of this type it is desirable to have the two jaws somounted that when they approach, each other they form an oblique anglewith each other in which the it outer ends of the jaws are closer thanthe inner ends, thereby producing a gripping action that will hold theimplement "in place and prevent it from accidentallyslipping.

The above and other objects that may become apparent as this descriptionproceeds are attained by means of aconstruction and anarrangement ofparts that will now be de-. scribed in detail, and for this purposereference will be had to the accompanying drawing in which theinventionhas been illustrated, and in which: V V

Fig. 2 is a side elevation similar to that shown in Fig. 1, but with thehandles broken away and the jaws in open position;

In the drawing reference numeral llindi cates a handle havinga hand gripportion'2 and an arcuate portion 3 which is curved on the arc of acircle. A jaw member 4 is provided at the end of the arcuate portion andthe side 5 of the jaw adjacentthearcuate portion coincides with aradiusof'thecircle of which the-arcuate portion formsa part Although theedge 5 is preferably radial, it 7 is not absolutely necessar y that thisshould be so as the implement will function in sub; stantially the samemanner, even' if this edge is inclined with respect to the radius ineither direction, although such inclination must' be somewhat limited. iJ

A second jaw member 6 is provided with a curved edge 7 whose curvatureis the same as that of the arcuate portion?) and is adapted to fitagainst the latter. This jaw member has an edge 8 that is preferablyradial with respect to thecurvature of the edge 7, but as explained inconnection with'the edge 5, edge 8 may vary from the radial to the sameextent as edge 5. a The secondjaw is provided on each side with a:groove 9-that is concentric with the curved surface 7 and attached tothe 'arcuateportion of the handle are lugsthat have inwardly projectingportions 11 that extend into the groove '9f1n the manner shownmore'clearly in Figx4l The lugs' 10 serve to hold the second jaw memberin position adjacentthe arcuate sur- 7 face 3, but permits the j awmember to move with respect to the handle member. It will be apparentthat if the curved surfaces 3,

and 7 are arcs of circles and if'th'e/edges 5 Y and 8 areradial withrespect to these surfaces, then when the second jaw member" is moved.alongthe curved surface alts mo-,

tion will be the same as if it turned about a pivot located at thecenter-of; the arcuate surface 3. From this it will be seen that whenthe two jaws are in the position shown in Fig. 1, the edges 5 and 8 areparallel,but

if the jaw member 6 is moved away from jaw member 4, then the two edges5 and 8 will thatthey intersect at the center of the are as; aboveexplained. For'the purpose ofmoving the jawmember 6, alever l2 hasj-beenbecome inclined to each other for'the reason component tending to rotatethelever 12.

Referring now more particularly to Figs.

1 and 2, it will be seen that whenthe handle 1 and the lever 12 areinthe positionshown in Fig. 1, the two jaw surfaces 5 and 8 are parallelwith each other and spacedi a short distance apart; It inightlbementioned here thattthis instrumentis not intended for cutting andtherefore the jaws must always be adjusted so that they will not bebrought into contact witheach other because'if this were doi1e,'it.would sever. the skinand'flesh interposed between them When the handleand lever are moved apart from each: other towards'the pesition shown win Fig 2,, the jaw 6= Willi be moved away iiror'n 4,. but

will follow the curved surface 3:.v Since the.

pivot 11 moves in the are of a circle whose center iseat thevintersection ofthe: aws- 5 and 8 extended, it is evident the pivot16slot 15 has been provided.

-J-S1ot'15 is so curved that when the jaws are brought to closedposition against some resistance; then the pressure necessary willbe'betwee n the convex side of theslot 15 and the pin 16 and by soforming thisslot that a line drawn through the pivot 16'andthrough thepivot 17 when the jaws are in closed position, will pass through the'center of curva ture'of'the slot, then a constructionis pro ducedinwhich the leverage increases as the. jaws approach each other andinwhichthe jaws become practically locked when in the position shownFig. 1, from which it will be seenithat with the partsadjusted in themanner idescribedand shown any-force tende ing to, separatethe jaws willnot have any In order'topermit the edges of the jaws to bee-properlyadjusted'so as-to obtain the most desirable results, an adjusting meanshas been provided which has been illustrated in Fig.5; From Fig. 5it'will be seen that thejaw member his provided withv an opening'18; inwhich is located a circular plug 19. Plug'19 is provided with aneccentric opening 20throughwhich the pivot pin 1Textends It is evidentthat by turning thelp ltrg 19 in the hole 18, the relationship oi theedge Set the jaw can be varied with respect to the pivot 17 .T 1 Y Fortherpurpose of adjusting the plug 19 in the ripening 18,-jaw memberhhasbeen pro-- 1. The ends of members 14 project forward-v vided with twoopenings 21 that are Preferably radial with respect to the opening 18and located in each of these openings is a threaded plug or screw 22.These screws have conical ends 23. The plug 19 is provided with conicaldepressions 24 into which the conical. ends 28 of the screws extend. Inthe form illussible by moving one of the screws outwardly and theotherinwardly, to effect a slight rotation of the plug 19, which issufficient to elfect the required adjustment oi theedges 8- 'and 5 oi?the jawsr v 1 r From the above description it will 'be seen that theimpleinentthat forms. the subject of this invention. is of a rigidconstruction and so formed that the j aws; as. they approach each other,are. closer together at the outside than atthe inside whereby a clampingaction is obtained that serves to hold the implement in place during theoperation. "lt will also be seen that by means ofthe constructionshownanddescribed the leverage is greatly increased as the jaws approacheach other this increase in leverage being dueto the straining ofthetoggle and also to the curvature of the slot 15. r V .f It is alsodesired to call attention atthis point to thefact that by removing thepivot pin l'Z thejaw 6 can be removed for cleaning 7 and it. istherefore possible to maintain this instrument in an antisepticorsterilized condition with less amount of labor and care than isnecessary with instruments that cannot be soreadilyseparated.

Particular attention is called to the fact that the two jaw surfaces .7and}? have a movement relative to. each other, that is to say as. ifrotated relativeto each other about the center of the arcuate suriace3..
